Siheyuan: Start with a Truck Driver

Chapter 701 Chip Project
conference room.

Under the surprised eyes of those researchers, Wang Weidong asked Yu Li to distribute the materials in front of them.

"Comrades, this is a blueprint of a minicomputer I personally designed, please take a look first."

Hearing this, the eyes of those researchers dropped in shock.

What a joke, the internal structure of the minicomputer is extremely complicated, even if they researchers have been studying it for so many years, they have only figured out some clues, and now the factory manager actually said that he has researched the minicomputer.

But seeing Wang Weidong's full confidence, they restrained their surprise and slowly opened the materials on the table.

The material is printed with ink.

There are not only texts on it, but also drawings.

It's seventy or eighty pages thick.

The researchers have all studied minicomputers, but after carefully looking through them, they can see the way.

Their expressions suddenly changed.

In this era, whether it is domestic or foreign, the research on minicomputers has just begun.

Many of the truths that seem to be very simple in the eyes of later generations belong to theories that have never been discovered in this era.

Such as the internal structure of the minicomputer.

In the past, researchers used to regard minicomputers as a whole and unified planning layout.

But in Wang Weidong's material, the minicomputer is divided into several parts.

For example, motherboards, power supplies, display CPUs... Of course, even if the CPUs of this era are researched, the graphics computing capabilities are not enough, so there is no graphics card.

This design scheme seems weird and cumbersome, but the researchers realized the benefits when they thought about it carefully.

If the minicomputer is considered as a whole, they must take all aspects into account when designing.

This will cause great difficulties in research work.

But now the miniature is divided into several parts, so they only need to conduct special research on these parts every time.

For example, the motherboard of a minicomputer.

They can directly set up a minicomputer motherboard research group to conduct research on the motherboard.

Design and manufacture the motherboard, as long as you are responsible for the corresponding standards.

And power.

As long as the power supply can provide a stable current, it is enough to meet the standard.

Of course the most important thing is the CPU.

Wang Weidong adopted a structure that they had never had in the design drawings of the CPU.

This architecture was named 8086.

It is an abbreviation for the standard number of the general-purpose computer family and also identifies a general-purpose set of computer instructions.

The biggest advantage of this architecture is portability.

The upgraded architecture is perfectly compatible with the old architecture.

As such.

Even if the CPU is updated, the original program can run on the new CPU, so there is no need to redesign the program.

In this way, a lot of waste of manpower and material resources can be avoided.

At this time, some researchers raised doubts.

"Factory Manager, in your design, the CPU is a computing software component, so what is this thing made of? Now many large laboratories abroad, and then there are research institutes, their computing equipment is It's a big tube."

"Yeah, even the calculator inside the mainframe of our wired power station is a vacuum tube."

"Looking at your CPU, it can be placed in a small box, which is enough to show that its area is small. How can it meet the needs of computing?"

As expected, a researcher who specializes in minicomputers can see the key points of the matter at a glance.

Whether it's the motherboard, the power supply, or the memory registers, they all work for the CPU.

If there is no CPU, then they are a pile of scrap metal.

In this era, there is no concept of CPU, and there are no chips of later generations, and some are just large electronic tubes.

Wang Weidong asked Yu Li to take a blackboard and write and draw on it calmly.

"Comrades, you may know what an insulator is, just like the wood in our rubber shoes is collagen. You may also know what a non-insulator is, just like wires, steel current can pass through easily."

"But there is another substance in this world called a semiconductor, which is a substance between a conductor and an insulator."

"Like the televisions and radios we commonly use, there are semiconductors in them."

"It's just that the semiconductor inside plays a relatively weak role, and only plays the role of signal conversion."

"Just imagine, if we use semiconductors to imitate electron tubes, what effect will it have?"

As soon as these words came out, the researchers were immediately stunned.

The semiconductor technology of this era is still very backward.

The semiconductors in a radio are just the humblest kind.

It is simply not possible to use semiconductors to perform computing tasks.

Otherwise, the research laboratories on the opposite side would not spend a lot of money to build electron tubes.

"How is this possible? What are the semiconductors in the radio doing?"

"Yeah, they can only handle simple signal welding machines, and cannot complete tedious calculation tasks."

"What was said in the materials just now is well-founded, but when it comes to the key CPU part, it seems a bit fanciful. I think this factory manager is a bit unreal."

Researcher Liu Chunyang was more sober than those researchers. He patted the table and said in a cold voice, "Everyone, stop arguing and listen to what the factory manager has to say."

Wang Weidong nodded at him and said with a smile: "The reason why the performance of the semiconductors in the radio is weak is that the density on them is not enough. If we can increase the density, then the computing performance of those semiconductors can be greatly improved. In the end It can achieve hundreds of millions, billions, and trillions of calculations per second.

"

This time the voice fell, and the researchers didn't say anything, and became thoughtful.

Yes, semiconductors can be carved infinitely.As long as densely packed circuit diagrams are engraved on it, miraculous effects can be produced.This has been confirmed by physicists.

It's just that no one thought of using semiconductors as a computing tool.

Wang Weidong continued: "So the key to the problem is how to manufacture high-speed computing semiconductors, which I call chips.

The next key work of our institute is to study how to manufacture high-speed computing chips. "

The results of scientific research are the results of countless failures. If someone knows the answer in advance, it will be much simpler.

The current domestic researchers are actually very strong. After hearing the concept of chips, they quickly understood the mystery.

Especially Professor Liu Chunyang.

He even came up with several plans in an instant.

Wang Weidong nodded in satisfaction when he saw the researchers talking about it.

Even if these researchers can't research anything, he can get a complete set of CPU drawings from the system.

It won't take long for the chip to be born in the research laboratory openly.

"Okay, now I order our laboratory to set up a chip research team. I will be the team leader. Liu Chunyang will be the deputy team leader."

Under the order of Wang Weidong, Lanhua Automobile Factory started the research work of the chip.

the other side.

Xu Damao also began to carry out Wang Weidong's mission, to find out how the Mediterranean Sea rescued Bangen.

He first started with Jia Zhang.

The old lady Jia Zhang, although she chatters a lot on weekdays, she actually doesn't have a lot of brains.

In particular, Xu Damao brought her a box of snacks.

Looking at the box of snacks, Jia Zhang couldn't close his mouth.

"Oh, Xu Damao, the sun really came out from the west today. After so long, you finally think of me, old lady."

Before Xu Damao married Qin Jingru, he was very kind to the Jia family.

After all, he used illegal means to get Qin Jingru back then. In order to get Qin Jingru's support, Xu Damao wanted to win over the Jia family.

In particular, he is also a projectionist, and every time he goes to the countryside to show a movie, he can get some good things from the countryside.

Things are not your own, so you won't feel bad when you give them away.

Peanuts, wheat, rice, pecans...they sent them to Jia's house with great enthusiasm.

But ever since he married Qin Jingru, it seemed as if he had forgotten about the Jia family.

Hearing Mrs. Jia Zhang's words, Xu Damao was not annoyed at all, and said with a smile: "Mr. Jia Zhang, now that the deaf old lady is dead, you are the head of the family in our courtyard. It is reasonable for me to honor you as a junior." As it should be."

Hearing this, Jia Zhang was so happy that he couldn't close his mouth from ear to ear.

In the past, in the courtyard, the deaf old lady ranked first, followed by the first mother, the second mother, and the third mother, and finally it was Jia Zhang's turn.

Now Xu Damao actually thinks that her status is higher than that of aunt, can she be unhappy?
"Oh, Xu Damao, your little mouth looks like honey. If I were to kill a pig, I would be so happy to have such a good mouth like you!"

Xu Damao took the opportunity to ask: "Mr. Jia Zhang, Sha Zhu will soon become your son-in-law, and he didn't give you any indication?"

Mrs. Jia Zhang rolled her eyes: "Don't mention that idiot Shazhu, as soon as I mention him, I get angry."

"What's the matter?" Xu Damao asked.

Mrs. Jia Zhang patted her thigh and said: "Silly Zhu is too insignificant. He is going to my house. I agreed with Qin Huairu, but he didn't show anything to my wife. Just yesterday I asked Shazhu Go to help me buy a cash register, but silly Zhu actually said that he has no money in his hand, do you think this is plausible?"

When Xu Damao heard this, he called him a good guy in his heart.

Now a radio costs more than 180 yuan.

Silly Zhu has no job, and eats and drinks Mediterranean.Where did he get the money to buy a radio for Jia Zhang.

Besides, even if Shazhu is rich.

He would not buy it for Jia Zhang, and he did not marry Jia Zhang, but Qin Huairu.

But Xu Damao is a smart person, of course he would not refute Jia Zhang.

He clenched his fists and said: "Shazhu is too shameless, you are Qin Huairu's mother, after Shazhu and Qin Huairu get married, you will be Shazhu's mother.

As a son, Shazhu should be filial to you.

Let alone a radio, even if it is a TV, Sha Zhu should buy it and give it to you immediately. "

Xu Damao's words touched Jia Zhang's heart.

Jia Zhang said with a cold face: "That's right. Silly Zhu is too insignificant. If he could not save my family, I would never agree to Qin Huairu marrying him."

Hearing this, Xu Damao took the opportunity to ask: "Jia Zhang, don't think I'm supercilious, Shazhu is just a fool, and he has no job now, how can he rescue the stick?"

Mrs. Jia Zhang laughed: "You don't know that. Although silly Zhu can't do it, there is still the Mediterranean Sea."

"Mediterranean is only in the neighborhood office, and he has some connections and is not familiar with the people at the police station. How can he save her?"

Jiazhang looked around and saw that Qin Huairu was not by her side. She lowered her voice and said, "Xu Damao, let me tell you something, but you must never tell Qin Huairu. Qin Huairu doesn't allow me to tell outsiders that I am here today. I'm telling you because you gave my old lady some snacks.

You must not embarrass me. "

Xu Damao patted his chest and said: "Ms. Jiajia, don't worry, I, Xu Damao, must have a tight mouth. When did you see that I betrayed others?"

Don't say it yet.

Although Xu Damao had betrayed so many people, he was very secretive, and the residents in the courtyard did not know about it.

Naturally, Jia Zhang didn't know either.

She said with confidence: "I heard from Qin Huairu that Mediterranean found a previous relationship with the deaf old lady. That person is a deputy director of the street office and has a good relationship with the comrades in the police station. He will definitely bring my family back. The stem will be back."

The deputy director of the street office... Xu Damao frowned and thought for a while, but he couldn't remember who it was.

He decided to tell Wang Weidong about it later.

At this time, Qin Huairu just walked in from the outside.

She also carried a lot of vegetables and a lot of meat in her hand.

obviously.

Qin Huairu is going to marry Shazhu soon, so he must have given her a lot of money as a bride price.

Seeing Xu Damao and Jia Zhang muttering there, Qin Huairu's heart hung in the circle of his throat, and he rushed forward and asked, "What are you two talking about?"

Xu Damao waved his hand and said, "I didn't say anything, I was just discussing how much gift money should I give you when you marry Silly Zhu?"

As soon as these words came out, Qin Huairu didn't care about the matter just now, and said excitedly: "Xu Damao, you are Qin Jingru's husband, and I am Qin Jingru's cousin. We are very close."

"General neighbors in our compound get a gift money of two yuan for marriage. For a relationship like ours, you have to get at least four yuan gift money."

Xu Damao took a deep breath: "Qin Huairu's gift money of 4 yuan, don't you think a little too much? You should know that my monthly salary is only more than 40 yuan."

Qin Huairu pouted and said, "Xu Damao, don't be dissatisfied. If I hadn't introduced Qin Jingru to you, would you have a child now?"

When she said this, she used a threatening tone: "If you don't want a child, I will go to your house in two days to persuade Qin Jingru to go to the hospital to kill the child."

Xu Damao's face suddenly turned livid.

His family is a single heir for three generations, so he expects the child in Qin Jingru's womb to carry on the family line.

Now that Qin Huairu actually threatened herself with that child, it's really disgusting.

He sneered twice in his heart: okay, if you threaten me, then I will let you guys not get married.

Xu Damao nodded at Qin Huairu and said, "Okay, I will give you a gift of 4 yuan when the time comes."
